A still further object of the invention is the provision of a simple and efficient mount ing` for the headlights which likewise serves zo to provide `a mounting for one of lthe op-r eratinp,` cylinders Yof the .hydraulic mecha*- coinmunieating with one-hranchlthereof a conduit V2Q and with, the opposite, branch` if i thereofa check valve inlet 2l., *Each end of the `cylinder has port opening .upwardll7 i through the wallsthereof and thesevportsjj nisin7 whereby the headlights are actuated."

IThese and other objects we attain bythe construction shown in thev accompanying drawings, wherein .for the purpose of illustration is shown a preferred embodiment of our invention and wherein Y Figure l is a plan viewvshowlng` a frame and portions of the fenders towhich have been applied dirigible headlight :mecha` nisin constructed in accordance with Aour invention Figure 2 is a front `elevation partially i hrolren showing the operating);` cylinder and its connections to the headlights; l p Figure 3 is anpelevation showing the power cylinder and its connection with the steering; mechanism;

at their outeryendsl are closed by rpet-cocks;VM 23. The outer end of the pin 18 has-connect,- ed thereto `one end of a pitinan` or connect-L ing` rodfft, the opposite endl ofl which is pivotally connected with thesteering arm." l1, so that as thisfsteering arnilisloscillated,

the piston is reciprocated. When; the steerf ing arin is at itscentral position or atthaty position in, which the Ywheels XV; `of the `ve-y `[80 hicle are positioned for straight ahead travel, 3 the pistonv is in itscentral position.`

Secured to the fenders l2 at its ends is an support in the forrn of aninvertedll in.;

crossvsection l This supportwhas secured/ 85 `within the channel thereof and Y atits, center-` a second or operating l cylinder, lgenerally Y Vdesignatedat 26. The operating .cylinder is identical in constructionppand size withfthe 27 of the piston 28. this-cylinderis diijeg The conduits 2O communicate with opposite ends ofthis-,cylinderandthe ends ofthe- `cylinder are provided withlvbleeding pet-if icou fr `cocks 30 similar to the pet-cocks 23 of the power cylinder. Securediito the ,supportsrm and more particularly to the front wall 31 thereof are vertically directed guides 32 100 fill (ill

interiorly hushed, at 33, to rotatably receive the standards oi headlights f5.3. Thrust bearings 3G between the lamp bases 37 and the upper ends of the guides 21,2 support the weight ot the lamps and any looseness may be taken up by a rod projecting troni the lower end ol" the standards 31.1. through a transverse brace 38 and having at its lower end a nut 39 adjustable against the lower tace of this brace. 'The wall 3l in alignment with each` guide is slottedY at 1 0 and each lamp standard 34 has secured thereto an arm el projecting into the channel of the siip port 25.

The head 29 is provided withV ball headed lugs 42, the outer ends of which are received in sockets `43 atthe adjacent ends of rods 414e, which sockets preferably include a springpressed movable wall 45 taking up wear and preventing any rattling or lost motion in operation. The ends otthese arms have a similarball and socket connection with the operating arms 41 of the lamp standards and it will be obvious that as the piston 28 of the operating cylinder moves, this motion will be transmitted to `the lamp standards through the rods dat and arms 4l, causing the lamps to oscillate and 4the beams thereof to remain at the same angle to the frame of the vehicle as the wheels 7;

It will be obvious that in operation, assuming the conduits and the ends ot' the cylinders to be coi'npletely filled with fiuid, any movement of thesteering arm 11 will cause an increase in pressure through one conduit 20 and `adecrease in pressure inthe opposite conduit 20 in the ends of the operating cylinder, "with theV result that the piston 28 of the operating cylinder will move syn-` chronously with the piston 15 of the power cylinder. r The inlet littings 21, together with theprovision ofthe pet-cocks 23 and 30, provide a means,` `whereby these spaces may be at all times kept filled with liuid.

This fluid is preferablya light lubricating oil or a mixture of a heavierlubricatingoil with alcohol `or some similar diluent In event `that due to breakage ol" the. con-,J

duit- 20 or `:tor any other reason the operatiring mechanism becomes ineffective, we provide means for locking the piston 2S' oit the' This means comprises a screw 46 `directed through the forward wall ofthe support in opposition tothe head 29 when the piston is in central position. This 'screw maybe held in adjusted positions by alock nut 47 and when turned inwardly toits fullest extent,

will havexit-s inner end engaged in a socket 48 formed in the head, with the result that this bend. `is held frominpvernent and the headlights may not turn, diie to the vibra tion ot the vehicle.

Since the construction hereinbefore set forth is capable ol a certain range of' change and modification withfnit materially depart# ing from the spirit ot the invention, we do not limit ourselves to 'such specific structure except as hereinafter claimed.

We claim 1. In operating mechanism for dirigible headlights, a pair of similar cylinders each having a piston therein, corresponding ends of the cylinders being in communication with oneanother, al connection between the piston of one cylinder and a reversely movable element of the steering mechanism of the vehicle whereby the piston is rccipi'oeatwl as the element is reversely moved, connections between the piston of the other of the.

cylinders and the `headlights whereby the headlights are oseillated as said piston is till reciprocated, the wall of the last named cyly inder having a longitudinally extending slot,` a pin extending through said slot and engaged with the piston of the cylinder and having in its outer end a head to which the headlights are operatively connected, a supi having a piston therein,corresponding' ends of the cylinders being in communication with one another, a connection between the piston of one cylinder and a reversely movable eloment of the steering-mechanism ofthe vehicle whereby the piston is reciprocated `as the elementis reversely moved, a housing for the other of the cylinders having means whereby :it may be secured to a vehicle to extend transversely thereof, vertically ex? tending guides carried by the housing adjuv cent opposite ends thereof` headlight standards rotatable in said guides and havingr arms extended through slots in the wall of the housing to the interior thereof, `connections between said arms and the piston ol' the last named cylinder, and means adjust able through the wall of the housing 'l'or locking the piston of the last named cylinder aga inst movement.
